Joel 1:4(King James Version)That which the palmerworm hath left hath the locust eaten; and that which the locust hath left hath the cankerworm eaten; and that which the cankerworm hath left hath the caterpiller eaten.

The learned Bochart, and others, are of the opinion that the four Hebrew words, {gazam, yelek, arbeh, chasil}, respectively rendered the palmer-worm, locust, canker-worm and caterpillar, denote four different species of locusts. See on Exodus 10:4
